BURNER ADJUSTMENTS:
NOTE:
Alfresco
grills are available with both U-burners and IR burners. The following instructions
apply only to the U-burners. IR burners do not require adjustment and need only be checked visually for
proper performance. On high, an IR burner should glow red evenly over its entire surface.
U-BURNER AIR ADJUSTMENT:
Each grill burner is tested and adjusted at the factory prior to shipment; however, variations in the local
gas supply, elevation and other factors might make it necessary to adjust the burners. The flames of the
burners should be visually checked and compared with Figure 4.
If any of these conditions exist, check if dirt, debris, spider webs, etc., are blocking the air shutter or
burner ports. Proceed with air shutter adjustment.
AIR SHUTTER ADJUSTMENT:
A sheet metal cap at the inlet of the burner called the “AIR SHUTTER” regulates the amount of air that
enters into the burner for combustion.
The air shutter is locked in place by a screw, which must be loosened prior to lighting the burner for
adjustment. The air shutter adjustment screws are accessible with a screwdriver by removing the burner.
Loosen the screw of the air shutter. Reinstall the burner. Make certain that the burners are sitting
properly on the orifices taking care not to move or damage the igniter electrode.
Light the burners and adjust according to the following directions:
• Turn the valve on “HI”, light the burner and allow it to “WARM UP” for 10 minutes.
• If the flame is yellow, indicating insufficient air, turn the air shutter counter-clockwise to
allow more air to the burner. *Caution, see note below.
• If the flame is noisy and tends to lift away from the burner, (WITH THE BRIQUETTE
TRAYS IN POSITION) indicating too much air, turn the air shutter clockwise to reduce
the amount of air to the burner.
• Retighten the locking screw of the air shutter cap.
*NOTE: Be careful, as the burner may be or will become very hot after lighting it.
AIR SHUTTER APPERTURE IS FACTORY SET TO APPROXIMATELY 1/2”
FOR LP & 5/8” FOR NG - MINOR ADJUSTMENTS MAY BE NECESSARY DUE
TO FACTORS SUCH AS HIGH ALTITUDE LOCATIONS.
